Abstract
Abstract Dibenzo-18-crown-6 was modified to a hydrophobic ionophore which was incorporated stably into a small unilamellar liposomal membrane of egg yolk lecithin. Vectorial sodium transport mediated by this ionophore through the membrane was measured directly by observing a 23Na NMR spectrometer. It was proposed that sodium efflux is balanced by potassium or lithium influx mediated by the ionophores through an ion-exchange mechanism.
